Jackson, after all, comes from a slightly older vintage, and was heavily involved in the most infamous brawl in NBA history, 2004's "Malice at the Palace."

As many in the Twittersphere launched attacks on James over his behavior, two comments on Jackson's Instagram post - from John Wall and LeBron's former teammate Kendrick Perkins - appeared to be critical of James as well.

For his part, Jackson further explained himself Sunday morning, posting in a video that he would never expect James and Paul to turn on each other.

"Y'all cannot expect LeBron James to fight Chris Paul," he said. "That's his buddy, they just do it different these days ... if y'all expected (LeBron) to jump in and swing on Chris Paul, y'all might be the dumbest people in the universe."
